Question

for each of the following complexes Hexaaquiron(iii)chloride and triacetylacetonatochromium(iii)
1. write the d electronic configuration
2. give the number and types of isomers, if any indicate whether the stereo-isomers are chiral

Answer 1

1. Hexaaquiron(III)chloride or [Fe(H2O)6]Cl3 - 4s03d5, triacetylacetonatochromium(III) or [Cr(acac)3] - 4s03d3
2. The iron(III) complex: [Fe(H2O)6]Cl3 no isomers. The chromium(III) complex: [Cr(acac)3] possesses two stereo-isomers (the complex is chiral)
